I really like entries #17, #18, #19, and #20. Of these four, I like #17 the best, but #19 is a close second. I like the use of the multiple rooftops, as well as the color. I like the company name closer together than with the large space between the "CR" and the "Houses".
On #18, I like how the tag line is underneath the main company name, I will say though, that the way the tag line is done on #19, even though it's on top of the company name, is done in such a way as not to detract from it. I like both #19 & #20, and am trying to decide which way I like the tag line better.
Entry #17, while still having all of the elements of the other similar entries, just seems a bit too spread out, although I really like the size of the rooftops. Perhaps if you moved the "CR" closer to "Houses"?
